Calling async functions from trunk

[emilk]

As I understand it, trunks one and only entrypoint is fn main, which cannot be async, which means we cannot call async code in trunk apps, which is sad.

This came up today when I realized eframe::start_web is now async (since emilk/egui#2107), and eframe_template uses trunk. (This async stuff was added in order to support WebGPU).

Hmm, this appears to be a misunderstanding. Trunk has nothing to do with the application which is ultimately executed/run in the browser. Trunk compiles and bundles assets, but does not dictate how the application itself is structured.

Any limitations on that front will be dictated by wasm-bindgen actually, which is the framework used to run rust wasm applications.

Please feel free to re-open if you think I have misunderstood your comments here :)

Ah, I see. Thanks for the clarification!

For posterity, here is the required fix: emilk/eframe_template#83
